Weight increase of the Mercedes-Benz Marco Polo, Horizon, Activity, V Class, Vito to 3450 KG or 3500 KG per expert opinion

More weight allowance for luggage and camping equipment: this vehicle-specific uprating can increase the maximum authorised mass of your Mercedes-Benz Marco Polo, Horizon, Activity, V-Class or Vito to 3,450 or 3,500 kg. Depending on the current authorised mass and the technical configuration, that represents an increase of 250 to 400 kg.

Vehicle-specific checks establish the right uprating

The uprating is intended for the listed models built from 2014 onwards with a current maximum authorised mass of 3,100 or 3,200 kg. The W447 and W639/2 series or type designations must be checked against the individual vehicle's VIN and registration documents. The suitability of both the vehicle and the proposed technical configuration must be established before the report is issued.

Four wheel and tyre combinations for 3,450 or 3,500 kg

The prerequisites are VB Airsuspension 4C suspension and wheels and tyres with the required load ratings. 1sternehotel offers this uprating only after installing both the suspension and the wheels in its own workshop. The following four configurations are specified:

Option 1, up to 3,450 kg: 18-inch Delta 4x4 Klassik B wheels with General Grabber AT3 235/55 R18 104 H tyres.

Option 2, up to 3,500 kg: 17-inch Delta 4x4 Hanma wheels with General Grabber AT3 235/65 R17 108 V tyres.

Option 3, up to 3,500 kg: 17-inch Delta 4x4 Klassik B wheels with Loder Tire AT#1 235/60 R17 118S tyres.

Option 4, up to 3,500 kg: 17-inch Delta 4x4 Hanma wheels with Loder Tire AT#1 235/60 R17 118S tyres.

Understand how much extra payload you can use

Starting from 3,100 kg, the authorised mass increases by 350 kg to 3,450 kg or by 400 kg to 3,500 kg. Starting from 3,200 kg, the corresponding increases are 250 and 300 kg.

These figures describe the increase in maximum authorised mass, not necessarily an identical increase in usable payload. The vehicle's actual weight after conversion is what matters. Any additional weight from retrofitted components must be taken into account, and the permitted axle loads must still be respected.

Keep the correct wheels fitted after uprating

The suspension, wheels and tyres must meet the load requirements of the uprating. Original Mercedes-Benz wheels and other wheels with insufficient load ratings must not be used after this uprating. Any subsequent wheel change must therefore comply with the increased authorised mass and the conditions of the report.

VIN-specific documents for the TÜV inspection

This item includes a technical report issued for your VIN and a new label showing the axle loads, gross vehicle weight and VIN for presentation to TÜV. The suspension and wheel set are prerequisites for the uprating, but are not included in this report item.

The report does not itself amend the vehicle's registration documents. The required technical inspection and the recording of the increased maximum authorised mass are further steps. If the vehicle is registered outside Germany, acceptance of the documents and local registration requirements must be checked beforehand.
